Idk if this is the appropriate place to post this but for some reason when my quad does this at max throttle it won't take off and the throttle cuts out. It also has almost zero throttle controll. It will either lag or the throttle will just go to max and the only way to stop it is to disarm it. The USB connector broke off so I have to get a new flight controller before it broke I tried resetting the firmware, adjusting the stick thresholds yet it still does this.

I'm also using the erls and I made sure that it power was in max. This is the flight controller I ordered.https://shop.iflight-rc.com/electronics-...er-Pro1662
Im thinking that it has something to do with the motor direction. However, I would love yall's input? Note I will not be able to post any betaflight stuff until the new FC arrives. 

Your two motors on the right side are spinning the wrong directions. They’re spinning as they would be in a “props out” configuration, but your props are in a props in configuration.

I can’t tell if your left front motor is also going the wrong direction.

Edit- if you’re comfortable soldering, you can change motor direction by swapping any two wires on the motors that are going the wrong way. (IE, front right motor is connected to the esc via 3 wires- desolder any two of those three and swap their position)
Edit edit- Hugnosed beat me to it while I was making that first edit.

it seems the left motors does spin the wrong way by watching the grass

if you dont have access to blheli configurator or suite, or bfc, you can change the motordirection by switch two motorwires.
desloder 4 wires, switch them and solder it back and you should be able to fly (if the direction matches the configuration, the actual info doesnt show if its setup as prop in or prop out. the default of betaflight would be props in, it would match to change the direction of the left motors than)
